Abstract:
A sacrificial anode (10) and method of making a sacrifical anode (10) are provided. The anode (10) includes an extruded galvanically active metal rod (12) and integrally formed end cap (14) which has a cylindrically shaped portion (28) with a threaded exterior surface. The anode (10) is formed by extruding the rod (12), forging the end cap (14) from the anchoring end portion (16) of the rod (12), and machining the outer surface of the end cap (14) to provide threads.
Abstract:
The invention relates to a hollow shaft (1) which on both ends has external profiling (2, 3) for the transmission of torque, shaft sections (4) lying therebetween having a smaller diameter than at least one of the profiled sections. The hollow shaft (1) can be or is assembled from two components (4, 12), one of which contains the shaft section (4) and the profile, as well as an outer, torque-transmitting profile (5) of a plug-in connector on the opposite side of the shaft to the profile, the other component being a bush-type component (12) with the second profile and an inner, torque-transmitting profile (6) of a plug-in connector.
Abstract:
Hohlwelle mit an ihren beiden Enden zur Drehmomentübertragung vorgesehenen besseren Profilierungen, wie Keilwellenprofilen, wobei dazwischen liegende Wellenbereiche geringere Durchmesser aufweisen als wenigstens eine der Profilierungen.
Abstract:
Methods of fabricating air-filled true-time-delay, continuous transverse stub array antenna. A plurality of extruded sections that are physically independent of one another are fabricated. The plurality of extruded sections are arranged in a predefined pattern defining the structure of the array antenna. Adjacent surfaces of the extruded sections form waveguides of the array antenna. The plurality of extruded sections are joined together at their respective ends to form the array antenna. The plurality of extruded sections may be joined using a plurality of end plates. The plurality of extruded sections and end plates may comprise metal or plastic. If the extruded sections are plastic, they are metallized (44) using a process such as vacuum deposition, electroless plating, or lamination during the extrusion process. The end plates are sealed to the extruded sections to form the array antenna structure.
